And if something does not suit the plant, it begins to instantly respond to external factors. A huge number of gardeners are faced with a problem that can affect the entire cucumber garden.

Cucumbers: yellow leaf edges. Why yellowing occurs

In order to correctly and timely start the fight against the appearance of yellow leaves on a cucumber bush, you need to get acquainted and study the reasons for the formation of this problem in your garden.

Cucumbers: yellow leaf edges due to unstable climate

Often, cucumber leaves begin to turn yellow due to unstable temperature conditions. Cucumbers do not tolerate cold weather and sharp drops in temperature, because of this, the leaves begin to turn yellow, and the plant itself stops growing and does not bear fruit well. If you grow cucumbers in greenhouse conditions, then you need to carefully monitor the temperature, directly in the room itself. The temperature should not be excessively high, this can lead to the appearance of a variety of fungi and viruses, and it can also provoke decay of plant roots.

Yellow edges of leaves in cucumbers due to incorrect selection

It happens that the wrong place for planting a vegetable crop becomes the fault of a change in the color of the leaves. To protect cucumbers from diseases, fungi, viruses and pest infestations, the site must be located in a well-lit area. But don't forget that light shade is also very important for plant growth. Following from this, the place for the cucumber bed should be partially shaded, this measure is needed so that cucumbers do not get burned during a drought or extreme heat and the leaves do not turn yellow.

Lack of food.
Every summer resident knows that the cucumber is very sensitive to the soil. Or rather, to the content of nutrients in it. If there is a nutritional deficiency or undernutrition, or the soil itself is poor and not fertilized, the leaves will begin to turn yellow and dry. This problem can arise when there is an acute shortage of nitrogen in the soil. If there is a very small amount of nitrogen in the soil, then the leaves will begin to take on a yellow color, and the fruits will resemble a hook in shape. If these signs appear in your garden, I advise you to immediately add fertilizer to the soil. I usually use 4 to 5 buckets of last year's rotted manure. To oversaturate the soil with manure is also not worth it, this can provoke the death of plants and a bad ovary.

Yellow edge on cucumber leaves due to improper or untimely watering

Yellow leaf edges can be closely associated with improper watering techniques or when watering is irregular and very poor. If the edge of the leaf began to turn yellow, you can be sure that these changes begin to occur due to a lack or excess of moisture, and all this is known to be incorrect watering. A very large number of gardeners water the cucumber garden little by little and often, this is absolutely impossible to do. If watering is done by this method. then the plants will lack moisture. All moisture will remain on the surface of the soil and the root system will be sorely lacking, since practically no water will get to the roots. The roots will gradually weaken, leading to the appearance of yellowed foliage on the plant's bushes. Therefore, dear gardeners, I advise you to very carefully follow the rules for watering a cucumber garden.

Cucumbers: yellow border around the edge of the leaf due to disease

Powdery mildew infection

Cucumber leaves may begin to turn yellow due to infection with a fungal disease such as powdery mildew. It is quite simple to understand that the garden bed has been affected by a fungus. At the very beginning of the onset of the disease, a white bloom, similar to small specks, begins to form on the leaves of the cucumber. The disease begins to affect plants from the lower leaves. After about 5 - 7 it, this disease is capable of infecting the entire bush as a whole. The edges of the leaf turn yellow, after the leaf dries and falls off. If you do not sound the alarm in time and take action, the plant will die without beginning to bear fruit. You can defeat powdery mildew. To do this, I use drugs such as Topaz or Zaslon, they have been tested more than once in the fight against powdery mildew and have shown excellent results. But it is worth remembering that these funds should be used before the first ovaries appear.

We treat fusarium

Also, the appearance of yellow and plow foliage on cucumbers can provoke a fungus such as fusarium. This disease clogs all the capillaries of the plant, and this greatly complicates the proper flow of nutrient juices from the stem into the foliage of the cucumber. The disease is very serious and dangerous, and even with the immediate detection and treatment of a fungal outbreak, the beds cannot be saved. If you notice that Fusarium is in charge of your garden, immediately eliminate the affected plants, this measure will prevent the fungus from spreading to all cucumber bushes and you will be able to save part of the crop.

In order to start processing plants from Fitosporin, a solution should be prepared. Usually I cook it like this, 20 gr. I deliver the drug in 5 liters of boiled cooled water and insist for no more than an hour. I process a cucumber patch once a week for a whole month.Treatments should be carried out in dry, calm weather, since the rain will wash the drug off the cucumber leaves and the positive dynamics of cucumber treatment will be lost.

The mixture must be used immediately since it is stored for less than a day, after this time the solution loses its properties and becomes useless. Processing is carried out in hot weather. There must be no wind, otherwise the mixture can get on other garden crops and cause irreparable harm to them.

Correct feeding.

Regular and high-quality feeding of the cucumber bed is the key to a plentiful and healthy harvest. It should be remembered that with a lack of nitrogen in the soil, the leaves change color and dry out. But at the same time, nitrogen fertilizing should not be done very strong and concentrated, this will also not lead to a good result. It is very simple to properly prepare a nitrogen-based fertilizing, it is enough to strictly observe the proportions. We take 30 gr. fertilizer and dilute it in 7 liters of water, mix well so that the solution is homogeneous. After you have applied fertilizer to the garden bed, spill the soil abundantly with warm water. Also, with the help of nitrogen-containing fertilizers, it is possible and necessary to carry out root dressing outside, in this case the solution is sprayed onto the outside of the leaf.
